In recent years, QR codes have become increasingly popular for their convenience in various tasks like accessing websites, downloading apps, and making payments. However, alongside their benefits, QR codes also pose a risk as they can be used in fraudulent schemes to steal personal information.
While QR code attacks are not new, they are becoming more sophisticated, with a recent scam called “brushing” emerging as a concerning threat. In this scam, individuals receive unsolicited packages with fake QR codes, leading them to unknowingly expose themselves to potential fraud when scanning the codes.
Cybersecurity firm NordVPN has observed a growing trend in fake QR code usage, estimating that over 26 million people may have been redirected to malicious websites through these deceptive codes.
According to Marijus Briedis, the chief technology officer at NordVPN, QR codes have become an unsuspecting tool for cybercriminals to exploit individuals’ trust. To mitigate risks, Briedis advises treating unexpected QR codes with the same caution as emails from unknown senders.
To stay safe from QR code scams, users are encouraged to verify the source of QR codes before scanning them, avoid opening suspicious links, keep security software up to date, use VPN when browsing, and educate others on potential risks.
While QR codes have revolutionized convenience in various aspects of life, it is crucial to exercise caution and verify the legitimacy of QR codes before scanning to prevent personal data theft.
The QR code, originally developed in 1994 by Masahiro Hara and his team at Denso Wave in Japan, was initially intended for efficient tracking of automotive parts. Over time, QR codes gained widespread adoption beyond manufacturing, extending to marketing, payments, tickets, and authentication, with a significant surge in popularity observed during the COVID-19 pandemic for contactless interactions.
